Technical notes

Open-source PICO-8 fantasy console reimplementation by Jacopo Santoni. Runs .p8 and .p8.png cartridge files. The PICO-8 font is compiled into the binary as a byte array (gen/pico_font.h, loaded in gfx.cpp:9). The Lua API shim is compiled as a string constant (gen/lua_api.h, loaded in lua_bridge.cpp:1126). The core never calls GET_SYSTEM_DIRECTORY and performs no file I/O from the system directory.

No BIOS or firmware files required.

Why no files

all engine resources (font, Lua API, color palette, audio synth) compiled into the binary
